i wouldnt say that right away just because there is a plahue consultant.
who knows what kind of plague the mogu or zandalari might unleash on us, instead the horde on them and the alliance.

all we can do is wait and see

Mogu don't need such crude and unsophisticated weaponry as plague, that's something emo zombies use when fighting directly fails miserably for them, as it often does. This plague consultant is rather clear. Teach the blood elves how to handle forsaken plague.

It seems I have missed that part. To me it seems they are pretty even.

Aside from the vast swathes of treasure and documents discovered by the Explorer's League during Classic and Wrath (As the Reliquary did not exist yet) heres what's current.

The Reliquary have made no gains in Uldum, whereas both Brann Bronzebeard and Harrison Jones - both members of the Explorer's League (Although Jones follows his own agenda.. still reports to Brann) have unearthed the near entirety of Uldum.

The Reliquary acted militant in Pandaria in search of artifacts for Garrosh, the one they DID find was destroyed by the findings of Explorer's League with the aid of Tyrande's forces.

The Reliquary's existance in Badlands and Krasarang serve as the opposition of the Explorer's League. In short, since Cataclysm Blood Elven lore has been built around being the direct enemy of the Dwarves (sorta like how Goblins can be seen as the direct enemy of Gnomes, and Humans with Orcs)

The Reliquary just doesn't have the knowledge and material that Explorer's League has, and I remember Blood Elves not enjoying digging in dirt as much as Dwarves do.

Not necessarily devastated, but the Dragonflight itself was dissolved by Kalecgos himself. If I recall correctly, it leaves each blue dragon to answer to no one unless by choice. Now one could say that since Kalec and Jaina are lovers, that Kalecgos who of course has his own friends and 'followers' has enough pull to bring in some kin to help in the conflict. The sticky part here is I do not see Kalec as an alliance figure, meaning his relationship towards Jaina is purely personal and not political. I could be wrong.

He joined the Kirin Tor, who are now Alliance, meaning he is as well.

He who sees his own doom can better avoid its path. He who sees the doom of others can deliver it.
